Fuel Injection Pump O Ring – Mopar (5086763AA)

Fuel Injection Pump O Ring pressurises fuel for the injection system. It is cooled and lubricated by the fuel it moves, which is why running a tank low shortens its life.

Replace the Pump O Ring when pressure is below specification with good voltage at the connector, when the pump is noisy and hot, or when it fails to prime. Check the relay and the ground before condemning it.

The Pump O Ring in this listing carries part number 5086763AA and sits in the Fuel Pumps & Senders category. The number stamped on the original part is the only reliable cross-reference.

This is genuine MOPAR stock, supplied for the Pump O Ring with the manufacturer number intact so the reference on the box matches the catalogue.
